Prevalence of lateral patellofemoral maltracking and associated complications in patients with Osgood Schlatter disease

A systematic review of imaging findings in patients with Osgood‐Schlatter disease

“…Only Pihlajamäki et al 14 obtained postoperative images after 10 years (6‐19 years) showing new ossicles in 44 knees (38%, Table S4). Another retrospective study by Kamel et al 12 found that 67% of those with residual OSD (aged 20‐50 years) had a single ossified fragment. The remaining either demonstrated multiple ossified fragments (21%) or fragments that had fused with the tibial tuberosity.…”

“…Of the studies that reported sex and age range, 70% were male, and 30% were female, with adolescents aged from 9 to 17 years. Five studies included adults with unresolved OSD aged 18‐39 years 11‐15 . Full study characteristics are summarized in Supplemental Material, Table S1.…”

“…Of the 40 studies included, 25 studies reported on OSD‐related imaging findings 4‐7,9,11‐30 . Most studies used radiography (n = 10) or US (n = 6), with the remaining studies using radiography and US (n = 4), radiography and MRI (n = 3), MRI only (n = 1) and one study using both CT, MRI, radiography, and bone scintigraphy (n = 1).…”

“…Five studies reported explicitly on imaging findings in an adult population with unresolved OSD symptoms 11‐15 (Table 1). Two retrospective studies with no control 11,14 reported that 93% and 100% of OSD had separate ossicles on pre‐operative radiographs.…”

“…Sixteen studies quantified anatomical and morphometric features proposed to be related to OSD 12‐15,20,24,30,32‐40 . Full details are outlined in Table 2 (patellofemoral characteristics) and Table 3 (tendon, attachment and tibial characteristics).…”
